. Specification of Letters Patent. Application filed November 27, 1911.

Patented July 29, 1913. .Serial No. 662,538.

tham, in the county of Middlcsex and State of Massachusetts, have invented certain new and useful Improvements in Looms, of which the following is a specification.

My invention relates to looms, and particularly to the head motion of a loom of the well known Knowles type, so-termed, shown and described in Elie-issue Letters Patent, N o. 7 ,78l, in which vibrator gears are moved according to the selection .of the pattern indicating mechanism, and brought into mesh with the upper cylinder gear, or the lower cylinder gear, and rotated thereby, in one or the other direction, to operate the harnesses, .or the drop boxes, in the usual way.

The obj set of my invention is to subst tute for the ordinary iron roller chain, a peg pattern chain, and provide mechanism which, through the indications of the pattern chain, causes the vibrator gears to be raised or lowered, and'brougiht into mesh with the upper cylinder gear, or the lower cylinder gear, and rotated thereby in one .or the other direction, to operate the barnesses, or the drop boxes.

My invention consists in certain novel features of construction of my improve ments, as will be hereinafter ,fully ;de

.scribed.

a front elevation of a Knowles head motion with -my improvements applied thereto. *Figg2lshowsthe-hea motion shown in F g.

l,a'par ;tially-;in section; some of the parts shown in Fig. 1 arelcft o f to more clearly I illustrate the operating mechanism of my improvements. Fig. .3 corresponds to F g.

thereon the stand or end frame 2, which supports the several parts of the head motion. The head motion shown in the drawings, is the well known Knowles type above referred to, and comprises the upper cylinder gear 3, fast on the cylindergear shaft 4, and the lower cylinder gear 5, :fast on the lower cylinder gear shaft '6. The vibrator lever 7 which is pivoted atone end on a stationary rod 8, carries the vibrator gear 9, which meshes with the upper cylinder gear 3, or the lower cylinder gear 5, by being raised or lowered by the pattern mechanism, to be hereinafter described, to communicate a reciprocating movement to the harness levers, or to the shuttle box motion levers, not shown, through the vibrator connector 10. A pinion 11 on the cylinder gear shaft 6, meshes with and drives a gear 12 loose on the shaft 13. All of the above mentioned parts may be of the usual and well known construction.

I will .now describe my improvements. On the end of the shaft 4of the upper cylinder gear :3 is in this instance secured a cam 14, which engages a roll 15, mounted on a stud 16 on a cam slide 17. A rod 18 is ad just-ably connected at one end to the slide 17, and at its other end is pivotally connected to a stud 19 on the end of one arm of a lever 20, whichhas its hub 20 mounted .on ,a transverse shaft 21. A helically coiled contraction spring 22 is attached at one end tothe arm 20, and at its .other end to a stud 23 .on the frame 2, and acts to yieldingly hold the roll 15 inengagement with the cam 14L. Through the revolution of the cylinder gear 3 and the shafte, the cam 14 causes a rocking motion to be communicated to the shaft 21. The shaft 21 has secured thereon, preferably at each end thereof, a vdownwardlyextending ,arm 24, which arms carry, at their lower ends, the knife bar 25, see Figs. 2 and 3 The knife bar 25 is adapt- .ed to engage the free notched ends 26 of the-connector fingers 26, when said fingers are in their lowered position, as shown in Fig. 3. The other end of the fingers 26 are each .pivotally connected to an arm 27, which has its open .end, or yoke shaped hub 27 loosely mounted on the shaft 13, and in this instance held thereon to prevent it from accidental removal by a split or cotter pin :Inthe accompanyingydrawings, 1 is a porition .of the loom sarch wh ch has mounted :27". A stud 28, .on each arm 27, carries a edge of the run 7 on the vibrator lever 7 and causes said vibrator lever to be raised, when the arm 27 is moved to the right, as shown in Fig. 3. The connector fingers 26 are raised and lowered through the indications of a pattern chain 30, comprising bars linked together, and carrying pegs 31. The chain 30 is carried on a cylinder 32, mounted on a shaft 33. The end of the shaft 33 has mounted thereon the gear 34, see Fig. 1, which meshes with and is driven by a gear 35, loose on the shaft 13, and fast to the gear 12.

A series of indicator levers 36 extend over the pattern chain 30, and are pivotally mounted on a transverse rod 37 at one end, which end has an upwardly extending arm 36 thereon, which carries an adjusting screw 38, which is adapted to travel on the lower edge of the connector finger 26, and orm an adjustable engaging surface between the indicator lever 36 and the connector finger 26. The extreme end 36 on the arm 36 extends above the lower edge of the connector finger 26, and a rib or flange 26", on one side of the connector finger 26, acts as a guide or bearing surface between said fingers, see Fig. 4. By means of the adjusting screw 38 any wear of the parts is provided for, and an adjustment may be obtained so that the levers 36 will always be properly alined for the bar 25. The free ends of the indicator levers 36 extend between pins 39 011 a comb bar 39; said bar limits the downward motion of said indicator levers at their free end.

To raise the indicator levers 36, to allow a peg 31 on the chain 30 to pass under said levers, I in this instance provide a transverse bar 40, which extends under the levers 36 at their free ends. The bar 40 is attached at each end to the lower end of an upright bar 41, which is pivotally attached at its upper end to an arm on the lever 20. A link 42, see Fig. 1, is pivotally attached at one end to the upright bar 41, and at its other end to the frame part of the head motion, and acts to hold the transverse bar 40 in proper position relative to the levers 36. A transverse rod 43 limits the rocking motion of the arms 27 see Figs. 2 and 3.

In the rotation of the pattern chain 30, when a peg 31 thereon comes under an in dicator lever 36, see Fig. 3, the lever 36 is raised at its free end, and the opposite end of said lever, which carries the screw 38 is moved to the right, and the notched end 26 of the connector finger 26 is allowed to drop down and engage the knife bar 25. The movement of the knife bar 25 to the right in Fig. 3, through the rotation of the cam 14, and intermediate connections, will move the arm 27 and carry the roll 29 under the run 7 on the vibrator lever 7 to raise the vibrator gear 9 into mesh with the upper cylinder gear 3, as shown in Fig. 3.

In the rotation of the pattern chain 30, when a peg 31 passes from under the pattern indicator lever 36, and a blank comes under said lever, see Fig. 2, the free end of the lever 36 will drop down and cause the end 36", carrying the screw 38, to be moved to the left, and the engagement of the extended end 36", with the rib 26 in the fin ger 26, will move said finger to the left, and draw the roll 29 from under the run 7 on the vibrator lever 7 to disengage it from said run 7, and allow the vibrator lever 7 to drop into engagement with the lower cylinder gear 5, as shown in Fig. 2. Thetravel of the lower edge of the finger 26 on the screw 38, will raise said finger out of the path of the vibrating knife bar 25, as shown in Fig. 2.

It will be understood that the details of construction of my improvements may be aried if desired.
